I bought a house a few months ago and I’m still trying to figure out all the wiring. I found these coming out of a cabinet in the kitchen.
I think (?) the black one is a cut-off coax cable. There’s a LOT of coax in this house, so that seems straightforward (but I would still love if someone can confirm!)
I’m not sure about the other ones. They don’t look electric, as I’d expect electric to be black + white + copper, like the rest of the house.
There is supposedly a speaker system in the house (I see speakers) but I haven’t figured it out yet. Could that be power for the speakers? I’m not familiar with speaker wire setup. If it’s speakers, why would there be so many wires?
Those look like a cable TV wire (the coax) and speaker wires. Get a non-contact volt sniffer (NOT a multimeter) to check for the presence of voltage in these before touching the conductors, but it looks like entertainment wiring to me. IMHO - I’m not a licensed electrician, so take this interpretation with a grain of salt.
